BACKGROUND ART

Generally, Internet banking is a service for realizing financial services through the Internet. Users can be provided with conventional Internet banking services after they apply to a corresponding bank for an Internet banking service, receive safety cards, access the Internet banking site of the corresponding bank, register as members and are authenticated with their safety cards. Further, users can be provided with each financial service by accessing a corresponding Internet banking site with respect to all established accounts using a similar process.

In conventional electronic commerce, the user pays for a commodity using a required account number at a corresponding electronic commerce site and then receives the commodity.

In this case, there are three kinds of payment methods, as fellows: first, a user can visit a bank and transfer money online, second, the user can transfer money using a cash dispenser, and third, the user can transfer money by accessing a favorable Internet banking site to transfer money using an Internet banking service.

Further, in order to pay for purchased products and various services such as traveling, lodging and restaurant services, the user can typically pay in cash or by a credit card.

The payment by a credit card can be used only in credit card affiliated stores, wherein the user can freely use the credit card within his credit limit, and the used money is paid together with a charge on a preset payment day.

The above conventional methods are problematic in that, since users must access the corresponding bank site to use the Internet banking service per established account, if there are many established accounts, it is very inconvenient, and a security problem of the Internet hacking, which frequently occurs, is not solved yet.

Further, when enterprises transfer money using the Internet banking service, since they have no internal control system for real-time money flow, money diversion and misappropriation by an accountant cannot be prevented.

Moreover, in the prior art, since a commodity purchaser confirms a delivered commodity after paying for the commodity in advance in electronic commerce, the purchaser cannot be guaranteed of the quality of the commodity, and his interest in Internet shopping decreases.

Finally, conventional payment methods are inconvenient in that users must carry cash providing against payment for transactions in affiliated stores, financial losses may occur due to the leakage of personal credit information of the user in paying by a credit card, and the payment is accomplished not in a timely manner but after a predetermined period of time elapses.

wireless application protocol (WAP) servers (or ARS servers) 6 through which a home delivery service provider accesses the integrated account managing service and managing a confirmation procedure so as to confirm that a purchased commodity is delivered to the user through the home delivery service provider.

The financial communication server 4 is connected to a financial telecommunications and clearings institute 7, thereby enabling the payment to be performed through affiliated banks 8, such as a shopping mall payment bank, an affiliated store bank and a transfer bank, and/or credit card companies.

The electronic slip processor B includes:

an electronic slip managing server 11 for generating an electronic slip and an electronic slip number using the identification (ID) and the password of the user when the user is desirous of the electronic financial transaction; and

communication server 12 connected to mobile communication service provider 21 for transmitting the electronic slip generated by the electronic slip managing server 11 to the communication system of the user.

The mobile communication terminal system A includes a mobile communication terminal 23 of the home delivery service provider, who subscribes to a plurality of mobile communication service providers 21 individually and delivers commodities, a mobile communication terminal 22 of the user who registers as a member and purchases a commodity or requests a financial transaction, a mobile communication terminal 24 of the manager who approves the financial transaction of an accountant managing settlements, and a mobile communication terminal 25 managed by the owner of the affiliated store, who sells commodities.

Further, a shopping mall owner, who subscribes to the Web server 1 as a member and sells commodities through a television and an Internet site, can be provided with the integrated account electronic financial transaction service under the same condition as the affiliated store 25. The mobile communication terminal system A may comprise a mobile communication terminal 26 managed by the shopping mall owner.

FIG. 3 is a flowchart of a process of confirming the account information by the user.

First, at step 100, the user accesses the Web server 1 to inquire about account, and if the user selects the website of an integrated account electronic financial transaction system, an input window is displayed at step 101. At this time, the user inputs information including his ID and password into the input window at step 102. The input window is shown in FIG. 8, and the information input into the input window will be used to generate a personal electronic slip.

The Web server 1 which controls the integrated account electronic financial transaction transmits the ID and password input by the user in the input window to the user managing server 2 at step 103, and the user managing server 2 determines whether the user is an authorized user at step 104. If the user is not an authorized user, the user managing server 2 makes the user confirm and input the ID and password again at step 105. On the other hand, if it is determined that the user is an authorized user, the user selects and inputs a type of service at step 106.

If, at step 107, the user selects and inputs an account information mode as the type of service, in order to inquire about account information, the Web server 1 transmits the user-inputted information including the ID and password to the electronic slip managing server 11 at step 108.

The electronic slip managing server 11 generates an electronic slip to which an electronic slip number is assigned and an advertisement using an embodied algorithm at step 109. The electronic slip with the electronic slip number is stored in a database within the server 11 at step 110, and is transmitted to the communication server 12 together with the telephone number of the user's mobile communication terminal 22 at step 111.

The communication server 12 transmits the electronic slip and the telephone number of the user's mobile communication terminal 22 to the mobile communication service provider 21 at step 112, and the mobile communication service provider 21 sends the electronic slip information to the user's mobile communication terminal 22 using a short message service (SMS) a step 113.

After the user confirms the contents of the received electronic slip and the advertisement at step 114, it is determined whether the user inputs the electronic slip number to the input field for the electronic slip number displayed on the website of the integrated account electronic financial transaction Web server 1 at step 115, and if so, it is then determined whether the electronic slip number inputted by the user is correct at step 116.

If the user does not input the electronic slip number, then at step 117, it is confirmed whether acknowledgement, which is a response method using WAP of the communication network, has been transmitted. If it is determined at step 117 that the acknowledgement has been transmitted, or if the input electronic transaction form number is correct (step 116), then it is confirmed whether the user is an authorized user at step 118.

The Web server 1 reads the account information of the user from the user managing server 2 at step 119, and transmits the account information to the financial communication server 4 at step 120, such that the financial communication server 4 reads the account information from a corresponding bank at step 121.

The Web server 1 receiving the account information of the user displays the information to allow the user to confirm it at step 122.

If the user confirms the electronic slip and advertisement using the short message service at step 114, first the contents of the electronic slip are displayed on the screen, and after confirming the contents of the electronic slip including the advertisement, the user can see the advertisement according to the guide such as “Click ‘yes’ if you want to see details of the advertisement” displayed at a lower portion of the electronic slip, as shown in FIGS. 4 a and 4 b.

Further, if the user selects a “yes” field and activates the advertisement using the WAP to see the advertisement, details of the advertisement are displayed using characters and images, as shown in FIG. 4 c. Moreover, a schematic map or details of the advertisement can be displayed at the lower portion of the electronic slip, as shown in FIG. 4 d. Therefore, the user can simply see the advertisement while clicking up/down fields using buttons of the mobile communication terminal.

Further, if the user clicks a telephone field displayed under the electronic slip or the advertisement, a telephone window is displayed, as shown in FIG. 4 e, thus enabling the mobile communication terminal of the user to be directly connected to the Internet or a corresponding telephone by the user clicking a MV code transmission field or buttons of his mobile communication terminal. Moreover, the display of the advertisement is ended by the user clicking an end field of the electronic slip.

On the other hand, for the electronic slip for payment approval, there are displayed a date, a serial number, titles of account of creditor and debtor, and transaction information by an automatic generation as shown in FIG. 4 a, while for the electronic slip for transfer approval in delivery, there are displayed an enforcement date, a title of account and transaction information by an automatic generation as shown in FIG. 4 b.

FIGS. 5 a and 5 b are flowcharts of a process of performing an account transfer service.

If, at step 131, the user accesses the Web server 1 and selects the website of an integrated account electronic financial transaction system, the Web server 1 displays an input window to the user using the short message service at step 132. The input window is the input window of FIG. 8 or the input window of FIG. 9. Information input to the input window of FIG. 8 is used to generate a personal electronic slip, and information input to the input window of FIG. 9 is used to generate an enterprise electronic slip. If the user inputs the user ID and password at step 133, it is determined whether the user is an authorized user at step 135.

If it is determined that the user is an authorized user at step 135, then at step 136 a Web site is displayed to allow the user to select and input a type of service in a of service selection field.

If the account transfer field is selected by the user at step 137, the account information of the user is displayed at the integrated account electronic financial transaction system website at step 138.

Accordingly, the Web server 1 displays transactable accounts of the user, such that, at step 139, the user selects an account from which to transfer money (which is required information), inputs a bank to which the amount is to be transferred (which is required input) and its account number at step 140, and inputs a transfer amount at step 141.

If the input process is completed at step 142, the Web server 1 transmits the information collected to the electronic slip managing server 11 at step 143. The electronic slip managing server 11, which receives the collected information, generates an electronic slip to which an electronic slip number is assigned and an advertisement at step 144 and stores the electronic slip information in the user managing server 2 at step 145.

At step 146, based on information in the electronic slip, the Web server 1 determines (on the basis of a payment limit amount) whether the transfer amount selected and inputted to the server by the user requires the approval of multiple managers. If multiple approvals are not required, the Web server 1 transmits both the electronic slip and the communication system number to the communication server 12 at step 147. The communication server 12 transmits the electronic slip to the user using the short message service through the mobile communication service provider 21 at step 148.

The user receiving the electronic slip confirms both the electronic slip contents and the advertisement at step 149. Then whether the electronic slip number has been inputted to the Web server 1 through the integrated account electronic financial transaction site is confirmed at step 150. If the electronic slip number has been inputted to the Web server 1, whether the electronic slip number inputted by the user is correct is checked at step 151.

If the electronic slip number is not inputted by the user, then at step 152, the Web server 1 confirms whether acknowledgement, which is a response method using WAP communication network of the mobile communication terminal, has been transmitted. If the acknowledgment has been transmitted, or if it is determined at step 151 that the electronic slip number input by the user is correct, then at step 153 it is determined whether the user is an authorized user. Then, the Web server 1, having confirmed that the user is authorized user transmits the contents of the account transfer to the financial communication server 4 at step 154. The financial communication server 4 requests the account transfer of a corresponding bank through the financial telecommunications and clearings institute 7 at step 55. At step 156, if the account transfer is completed, then the transferred result is displayed through the integrated account electronic financial transaction system website, thus allowing the user to confirm the transferred result at step 157.

If, at step 146, it is determined that the transfer amount requires the approval of multiple managers of the enterprise on the basis of the payment limit amount, then the enterprise manager clicks a “yes” field representing that additional transaction information will be inputted to the input window, and then the account transfer is performed after the contents of the account transfer are confirmed under the approval of multiple managers according to the accountant approval procedures of the enterprise.

Specifically, in order to make the manager of the enterprise confirm the contents of the account transfer, the user managing server 2 transmits the contents of the electronic slip and the communication system number of the manager to the communication server 12 at step 158. Then, the communication server 12 transmits the electronic slip to the manager using the short message service through the mobile communication service provider 21 at step 159.

After the manager receiving the electronic slip confirms both the contents of the electronic slip and the advertisement at step 160, if there is any fault in the contents at step 161, the enterprise manager stops the transaction at step 162. On the other hand, if there is no fault in the contents, the integrated account electronic financial transaction Web server 1 makes the WAP server (ARS server) 6 approve the transaction through the mobile communication service provider 21 at step 163.

It is confirmed whether the additional approval of another higher manager is required at step 164, and if the additional approval is required, the approval of the higher manager is achieved by the above procedures from steps 158 to 164. Meanwhile, if the additional approval is not required, the processing step returns to step 147 to identically execute the remaining steps.

FIGS. 6 a and 6 b are flowcharts of a process of payment by the integrated account electronic financial transaction site in electronic commerce.

At step 170, the user purchases a commodity from the shopping mall owner 26 who sells commodities through television or Internet sites. Then, at step 171, if the user selects to pay through the integrated account electronic financial transaction Web server 1, the user's mobile communication terminal 22 is connected to the integrated account managing Web server 1 at step 172. At this time, an input window is displayed on a monitor of the user's mobile communication terminal 22 at step 173. Information input into the input widow is used to generate the personal electronic slip or the enterprise electronic slip.

At step 174, the user inputs the user ID and password to the input window. If the user is confirmed as an authorized user at step 175, then the user selects a kind of service at step 176.

If the user selects an electronic commerce payment service of a variety of services at step 177, the integrated account electronic financial transaction Web server 1 displays account information of the user at a corresponding site at step 178. The user as a purchaser selects a payment account at step 179, and inputs the payment amount at step 180.

Then, if the user inputs the code number of the shopping mall owner or the account number of the affiliated store at step 18 the collected information is transmitted to the electronic slip managing server 11 at step 182. Then, at step 183, the electronic slip managing server 11 generates the electronic slip in which the electronic slip number is recorded and the advertisement, and stores them in the user managing server 2 at step 184.

The electronic slip managing server 11 transmit both the contents of the electronic slip and the communication system number of the user (e.g., the telephone number of the user's mobile communication terminal 22) to the communication server 12 at step 185, and the transmitted contents are sent to the mobile communication service provider 21 at step 186.

Then, the mobile communication service provider 21 transfers the electronic slip to the user at step 187. After the user receiving the electronic slip confirms the contents of the electronic slip and the advertisement at step 188, it is confirmed whether the user inputs the electronic slip number to the Web server 1 through the integrated account electronic financial transaction site at step 189. If the electronic slip number is inputted, then at step 191, it is checked whether the electronic slip number inputted by the user is correct.

If the user does not input the electronic slip number, it is checked whether the acknowledgment, which is a response method using WAP of the communication network of the mobile communication terminal, has been transmitted at step 190. If the acknowledgment has been transmitted, or if it is determined at step 191 that the electronic slip number input by the user is correct, then at step 192 it is confirmed whether the user is an authorized user.

The integrated account electronic financial transaction Web server 1 deposits the amount of money withdrawn from the payment account of the user, while storing the contents of payment in the deposit account managing server 5 at step 193. Further, the Web server 1 transmits the deposit result to the electronic commerce shopping mall owner at step 194, and after confirming the reception of the deposit result, the electronic commerce shopping mall owner delivers the purchased commodity to the user through the home delivery service provider at step 195.

The home delivery service provider delivers the purchased commodity to the user at step 196. The user checks the quality condition of the commodity at step 197, and if there is no fault in the commodity, the user draws the delivery receipt confirmation at step 198.

During the drawing of the delivery receipt confirmation by the user, the home delivery service provider accesses the mobile communication network using the WAP, and then accesses the WAP server (ARS server) 6 of the integrated account electronic financial transaction Web server 1 at step 199 to inform the WAP server of the completion of the delivery at step 200.

The Web server 1 confirms the delivery completion result and transmits a delivery electronic slip and an advertisement to both the user and the home delivery service provider using the short message service at step 201. The user confirms the received delivery electronic slip through the user's mobile communication terminal 22 at step 202, and then transmits the electronic slip number using WAP at step 203, thus enabling the transaction to be authenticated at step 204.

If the user does not transmit the electronic slip number, the home delivery service provider confirms and transmits the delivery electronic slip of the user to the WAP server 6 through the mobile communication network at step 205, such that the authentication procedure can be performed at step 204.

Here, a code number is omitted in the electronic slip transmitted to the home delivery service provider and is transferred from the user receiving the electronic slip in which the code number is recorded, such that the authentication can be achieved only after the commodity is delivered normally to the user.

The authenticated transaction contents are confirmed by informing the deposit account managing server 5 of the contents of a corresponding transaction by the WAP server (ARS server) 6 at step 206.

If the confirmation of the delivery receipt is completed, information on the deposit amount and the payment account is transmitted to the financial communication server 4 at step 207. The deposit account managing server 5 requests the account transfer of a corresponding bank at step 208, such that the payment amount is transferred from the corresponding bank to a bank having a receipt account at step 209.

The home delivery service provider transmits the delivery receipt confirmation to the electronic commerce shopping mall owner at step 210, and the electronic commerce shopping mall owner transmits the delivery receipt confirmation to the integrated account electronic financial transaction Web server 1 at step 211.

FIGS. 7 a and 7 b are flowcharts of a process of payment using the user's mobile communication terminal 22 when the user purchases a commodity, has a dinner in a restaurant and uses various services.

First, if the user accesses the WAP server (or ARS server) 6 through the integrated account electronic financial transaction system Web server 1 using the user's mobile communication terminal 22 at step 221, the communication system of the user is connected to the WAP server (ARS server) 6 at step 222. An input window is displayed at step 223 to allow the user to input his ID and password. The information input is either the input window shown in FIG. 8 or the input window shown in FIG. 9. Information input into the input window of FIG. 8 is used to generate a personal electronic slip and information input into the input window of FIG. 9 is used to generate an enterprise electronic slip.

Therefore, the WAP server (ARS server) 6 confirms whether the user is an authorized user through the user managing server 2 at step 224, and if it is confirmed that the user is an authorized user, the WAP server 6 makes the user select and input mobile communication system payment as the type of service at step 225.

If the selection is performed at step 226, the user selects the payment method at step 227, and inputs the payment amount and the payment contents at step 228.

The payment contents include affiliated store codes of affiliated store owners, which provide services like a food service, a television home shopping, and a communication catalog sales service, and commodity order codes.

Next, the user inputs an affiliated store code or an account number to which the amount is paid at step 229, and the affiliated store managing server 3 confirms whether the inputted code is that of the registered affiliated store at step 230.

If the inputted code is that of the registered affiliated store according to the confirmation result, the WAP (ARS) server 6 transmits the information on the payment account and payment amount to both the user managing server 2 and the affiliated store managing server 3 at step 231

If the user is disconnected from the WAP server 6 to wait for an electronic slip at step 232, the inputted information is transmitted to the electronic slip managing server 11 at step 233. The electronic slip managing server 11 generates an electronic slip, in which an electronic slip number is recorded, and an advertisement at step 234, and the electronic slip with the electronic slip number is stored in the user managing server 2 and the affiliated store managing server 3 at step 235.

The communication system numbers of both the user's mobile communication terminal 22 and the communication terminal 25 of the affiliated store owner are transferred to the communication server 12 together with the electronic slip at step 236. The communication server 12 transmits the electronic slip to both the user's mobile communication terminal 22 and the communication terminal 25 of the affiliated store owner 25 using SMS through the mobile communication service provider 21 at step 237.

Here, a code number is omitted in the electronic slip transmitted to the affiliated store owner and is transferred from a user receiving the electronic slip in which the code number is recorded, thus enabling the authentication to be performed only after a normal transaction is accomplished.

If the user informs the affiliated store of the electronic slip number, the affiliated store confirms the electronic slip by a slip number confirmation program and then inputs the electronic slip number to the affiliated store communication system at step 238, such that it is confirmed whether the electronic slip number is correct at step 239.

If the electronic slip number is not inputted at step 238, it is confirmed whether the user has transmitted an acknowledgment through the mobile communication terminal using WAP at step 240.

If the electronic slip is not correct at step 241, the affiliated store requests a payment in cash and ends the payment process at step 242. On the other hand, if the electronic slip number is correct or the acknowledgment has been transmitted (step 240), the affiliated store transmits the acknowledgment result to the integrated account electronic financial transaction Web server 1 through the communication system at step 243. The communication server 12 confirms the received contents at step 244, and then instructs the transfer of the payment amount from the user's account to the affiliated store owner's account at step 245.

The integrated account electronic financial transaction Web server 1 transfers the payment information to the financial communication server 4 at step 246, and the financial communication server 4 requests the payment from a corresponding bank at step 247. The corresponding bank pays the amount of money to a receipt bank by money transfer at step 248, and then transfers the paid result to the integrated account electronic financial transaction Web server 1 to inform the user and the affiliated store of the paid result at step 249.

The payment is described only for an example of payment by cash or debit card; however, if the user desires to pay by his credit card, authentication by the electronic slip is performed, and then the payment is processed in connection with typical credit card payment systems.

INDUSTRIAL APPLICABILITY

As described above, the present invention provides an electronic financial transaction system and method of providing a real-time authentication service through a wire/wireless communication network, which has an electronic slip function connected to a mobile communication system, thus allowing electronic financial transaction users to perform electronic financial transactions safely, conveniently, and rapidly by securing and authenticating the electronic financial transaction in real time through the electronic slip without temporal and spatial restrictions. Further, an approval authority (user) can approve payments in real time without temporal and spatial restrictions, so a leakage of information, or diversion and misappropriation of money can be prevented.

Further, the present invention is advantageous in that flows of commodity purchase and delivery are achieved in electronic commerce such that a conventional method such as payment in advance and deferred commodity confirmation can be changed to a method such as deferred payment and commodity confirmation in advance using electronic slips connected to a mobile communication system, thus increasing mutual reliability between users and electronic commerce shopping mall owners to activate the electronic commerce.

Further, the present invention is advantageous in that, since typical transaction amounts of money can be paid using mobile communication systems, a mobile communication terminal can be used as cash within a limited amount of money (including the credit transaction amount) of a user account. Further, since the user does not need to carry cash, the present invention can provide convenience and safety. Moreover, financial losses due to the leakage of personal information of the user can be prevented, and transaction and payment can be carried out in a timely manner in a viewpoint of the affiliated store owner, thereby increasing commercial transactions.
